We had difficulties finding the apartment, because "Rechte Wienzeile" changes its name, then changes back; and after we obtained the keys from the Restaurant on the ground floor, we did somewhat regret that we had to carry all the suitcases up to the third floor. But once inside the apartment, we found it good, and convenient, and if one keeps the windows closed, it is quiet even though the subway line runs directly below the windows. Walking through the Naschmarkt outdoor market to the city center is a nice fifteen-minute walk, so all the sights in the old city are in walking distance. We would use this apartment-hotel again if we come again to Wien.
